Filed: 1987-12-26
Abstract: PURPOSE:To improve the detected waveform of an identifying pit, and to prevent a track beam spot from being influenced by a preformat data pit by multiplying a data signal detected from a data signal detecting means and a track signal detected from a track signal detecting means. CONSTITUTION:A track beam 12 and a data beam 13 emitted from an optical system 1 are reflected by an optical card 2, returned to the optical system 1 again, and guided to a photo detector 3. The photo detector 3 sends the information of the optical card included in the track beam 12 and the data beam 13 to an I/V converter 4 for the track beam and an I/V converter 8 for the data beam, and an analog track signal and an analog data signal formed. After passing through a low pass filter 9, the analog data signal is sent to a multiplier 5, and multiplied by the analog track signal. Thus, the detected waveform of the identifying pit is improved, and the track beam spot is not influenced by the preformat data pit.

Abstract: PROBLEM TO BE SOLVED: To shorten time required for the automatic focusing of a color digital camera by calculating two focusing signals by using two spectra whose focuses are different and deciding a correct direction where a lens system should be moved so that the focus may be optimally set. SOLUTION: Signal strength is calculated concerning the spectra 1 and 2 at a present lens position (402). Next, the signal strength is compared between two spectra (404). When the signal strength of the spectrum 1 is larger than that of the spectrum 2 and a difference between them is larger than an amount X, a lens is moved in one direction (406). When the signal strength of the spectrum 1 is larger than that of the spectrum 2 and the difference between them is smaller than the amount X or when the signal strength of the spectrum 1 is smaller than that of the spectrum 2, the lens is moved in an opposite direction (408). Thus, the correct direction where the lens should be moved so that focusing may be optimally performed is decided.
